U4-5036FRN

Identical Dimensions

Same diameter, height and connections as standard units

for ease of installation.

Defender Combustion Chamber—Incorporates the Advanced ScreenLok® Technology Flame Arrestor and large split-door design to prevent ignition of flammable vapors outside the water heater.

Ultra Low NOx Burner with Primary and Secondary Air Distribution Devices—Ensures proper air to gas ratio for reduction of NOx generated by the combustion process.

Digital Thermal Sensor and Resettable Thermal Switch—Coordinates with self diagnostic control to prevent water heater operation as needed.

Millivolt Powered Control with Built-inPiezoIgniter—Easy and quick lighting of the pilot burner by push button.

Pedestal Base—Ruggedand durable base allows easy transport and positioning, and corrosion resistant contact with floor.

Maintenance Free—Noregular cleaning of air inlet openings or flame arrestor is required under normal conditions.

Sight Window—Offersa view into the combustion chamber to observe the operation of the pilot and burner.

No Electricity Required.

Factory Installed Hydrojet® Total PerformanceSystem—Cold water inlet sediment reducing device helps prevent sediment build up in tank. Increases first hour delivery of hot water while minimizing temperature build up in tank.

Vitraglas® Lining—BradfordWhite water heater tanks are protected from the corrosive effects of hot water by an exclusive ceramicporcelain-likecoating.

Self Diagnostic Honeywell Gas Control—Integrated, immersion gas control learns and monitors the combustion chamber's temperature profile and prevents water heater operation during upset conditions. Also equipped with an LED display to aid in start-up and diagnostics.

2" Non-CFC Foam Insulation—Surroundsthe tank surface, saving energy by retarding loss of heat.

Water Connections—3⁄4"NPT factory installed true dielectric fittings extend water heater life and eases installation.

Factory Installed Heat Traps—Designincorporates a flexible disk that reduces heat loss in piping and eliminates the potential for noise generation.

Protective Magnesium Anode Rod—Provides added protection against corrosion for long trouble-free service.

3x4 “Snap Lock” Draft Diverter—Allows either 3" or 4" vent connections with inputs of 40,000 BTU/Hr. or less.

Flue Baffle—Maximizesthe amount of heat absorbed by the tank and reduces heat loss during standby periods.

Steel Tank—Heavygauge steel automatically formed, rolled and welded.

T&P Relief Valve—Included.

Brass Drain Valve.

Meets C.E.C. Title 24, and SCAQMD Rule 1121 (10ng/J NOx limit).

Design Certified by CSA International (formerly AGA/CGA).

Minimum Energy Factor of 0.62.
